Thanks for the trailer!
Hmm - looks like the movie is going to be a big collection of rom-com clichés, and some of the lines in the previews are terrible. BUT - I liked Chris in what I saw, and the age difference between him and Haylie and which I thought would be an issue, doesn't show that much.
I'm not sure about the acting overall, but I'll give the film a try when it comes out.
